if i were to add the street series one on to say an AA exhaust... will it be much louder than if i did not add the x-pipe at all or does it dampen the sound a little....

which will be softer the street x-pipe + AA Exhaust or sports w/ high flow cats + AA exhaust or just the AA exhaust rear section

TIA
